Sweet Potato Dessert Squares

I prepare sweet potatoes every week for my family, mostly as a side dish. But I've found this vegetable also makes desserts even more delightful. These moist, rich square have a great pecan crunch.—Betty Janway, Ruston, Louisiana

    I also was searching for a way to use up some baked sweet potatoes. I made it in two 8x8 pans. The crumb base, was not really crumbly for me, more like a thick cake batter, but that is ok. Perhaps the egg was too large, or the new cake mix packages have less ingredient. I added toffee chips to the topping instead of nuts for my family- it is a lovely dessert

    I decided to prepare this recipe as I was looking for a way to use potatoes in this week's recipe ingredient challenge! This week's challenge called for potatoes-either regular or sweet! I had a can of yams and since I was also in the house on account of Ol' Man Winter, I thought I would put my time to good use! I HAVE made recipe adjustments: I used the 29-oz. can of yams, drained, 2 Tbsp. ground orange, I also used EVAPORATED milk instead of regular milk, and also used 1/4 cup each packed light brown sugar and white sugar to = 1/2 cup, 1/2 tsp. salt and for the spices, I used 1 tsp. ground cinnamon, 1/2 tsp. ground ginger, 1/4 tsp. each ground nutmeg and cloves for gentle seasoning. I used 1/2 cup melted butter for the crust and I used 6 Tbsp. margarine for the crumb topping. I used 1/2 cup chopped nuts (combined pecans/walnuts), rather than 1 cup! (I like to conserve on my nut supply, so I used less nuts) I also used 1/4 cup cinnamon-sugar in the topping mix. I greased and floured my baking pan for easier removal of the squares! I baked 60 to 65 minutes as recipe states! I'm certainly sure that this recipe will be delicious! Thank you, Betty Janway, for sharing this recipe with Taste of Home! This is also a great way to utilize sweet potatoes! I didn't garnish with any whipped cream or the pecan halves-I left dessert as is! This is a recipe which will be on my agenda to use again! I did notice that the quantity was more than 16 servings! I cut the dessert into squares and the amount made about 25 squares! I just might work on this recipe more-perhaps bake the crust about 10 minutes, then pour the filling over the crust and bake about 50 minutes. I'll keep trying-I did find the taste delicious! delowenstein

    While searching for a sweet potato pie recipe I came across this and decided to try it instead - was I glad I did! So delicious and different. Will be great for holiday time. The topping with the pecans adds such a wonderful taste. Will for sure be making this one again! Thanks for sharing Betty!
